DOI: 10.31399/asm.tb.tt2.t51060251
EISBN: 978-1-62708-355-3
... Abstract High strain rate tensile testing is used to understand the response of materials to dynamic loading. The behavior of materials under high strain rate tensile loads may differ considerably from that observed in conventional tensile tests. This chapter discusses the processes involved...
